我檢索圖像名稱的字符串,並具有從服務器下載 位對於使用這個鏈接獲取圖像名稱的字符串弗朗JSON數據和下載:多線程下載圖像會導致內存不足異常
字符串str_ImgURL_bmp_pattern =「http://xxxx/xxx/MobileService.svc/DownloadFile/FileName/」+ imageName; download_PngFile(str_ImgURL_bmp_pattern);
void download_PngFile(String fileUrl) {
Log.e("In download_PngFile ", " str_imgList_imageaudioPath = " + imageName);
Bitmap imagenObtenida = null;
try {
URL ImgUrl = new URL(fileUrl);
HttpURLConnection conn = (HttpURLConnection) ImgUrl.openConnection();
conn.connect();
imagenObtenida = BitmapFactory.decodeStream(conn.getInputStream());
//Log.e("imagenObtenida", " = " + imagenObtenida);
String fotoname = imageName;
File file = new File(newFolder, fotoname);
int sizeOfImage = (int) file.length();
Log.e("sizeOfImage ", " = " + sizeOfImage + "@ " + imageName);
if (file.exists()) file.delete();
try {
FileOutputStream out = new FileOutputStream(file);
imagenObtenida.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
// Log.e("Png = ", "DownLoad complete");
} catch (Exception e) {
}
} catch (IOException e) {
e.printStackTrace();
}
}
但是,這一些圖像下載和應用程序崩潰後,我得到的錯誤標題在logcat。

在此行中的錯誤:imagenObtenida = BitmapFactory.decodeStream(conn.getInputStream());
如何解決此問題。
